Description

この発明は、自動２輪車、自動３輪車あるいは４輪バギー車等のチェンジ装置に関するものである。   The present invention relates to a change device such as a motorcycle, a three-wheeled vehicle, or a four-wheeled buggy.

一般に、自動２輪車等においては、チェンジペダルを有し、そのチェンジペダルの引き上げあるいは押下げにより変速操作軸を回動させてシフトチェンジするようにしている。   In general, a motorcycle or the like has a change pedal, and a shift operation shaft is rotated by raising or lowering the change pedal so as to perform a shift change.

上記のような足踏み操作式のチェンジ装置においては、シフトチェンジの都度、チェンジペダルを操作する必要があるため、ドライバの負担が大きい。その負担を軽減し、かつ快適性の向上を図るため、特許文献１では、手元スイッチの操作により往復動型モータを駆動し、そのモータの回転によりカムプレートを揺動させ、このカムプレートにより変速操作軸に固定された中間レバーを揺動させて、変速操作軸を回転させるようにしたチェンジ装置を提案している。
特開平８−９３９１５号公報 In the stepping type change device as described above, it is necessary to operate the change pedal every time a shift change is performed, so that the burden on the driver is large. In order to reduce the burden and improve comfort, in Patent Document 1, a reciprocating motor is driven by the operation of a hand switch, and the cam plate is swung by the rotation of the motor. A change device is proposed in which an intermediate lever fixed to an operation shaft is swung to rotate a speed change operation shaft.
JP-A-8-93915

ところで、上記チェンジ装置においては、従来の足踏み操作式のチェンジ装置に組込み可能であって、足動作および手元スイッチ操作のいずれでもチェンジ操作が可能であるが、ミッションケースに固定された取付プレートにボルト支軸を設け、そのボルト支軸によってカムプレートを揺動自在に支持し、上記カムプレートに固着されてボルト支軸を中心に回転可能なドラムと往復動型モータにより回転されるドラムとの間に２本のワイヤをかけ渡した部品点数も多い構成であるため、コストが高く、組付けに手間がかかる問題がある。   By the way, the above change device can be incorporated into a conventional stepping type change device and can be changed by either foot operation or hand switch operation, but a bolt is attached to a mounting plate fixed to the transmission case. A support shaft is provided, and the cam plate is supported by the bolt support shaft in a swingable manner. Between the drum fixed to the cam plate and rotatable about the bolt support shaft and the drum rotated by a reciprocating motor. Further, since the number of parts over which two wires are routed is large, there is a problem that the cost is high and the assembly is troublesome.

また、チェンジ装置が大型化するため、特開２００５−６７４５０号公報に記載されたクラッチ装置を採用した自動２輪車に適用しようとした場合、自動２輪車の車両サイズ上、適用することが困難である。   Further, since the change device becomes large, when it is intended to be applied to a motorcycle employing a clutch device described in Japanese Patent Application Laid-Open No. 2005-67450, it may be applied due to the size of the motorcycle. Have difficulty.

この発明の課題は、部品点数の少ない簡単な構成の小型のチェンジ装置を提供することである。   An object of the present invention is to provide a small change device having a simple configuration with a small number of parts.

上記の課題を解決するため、この発明においては、変速操作軸の回転によってシフトチェンジする自動２輪車等のチェンジ装置において、前記変速操作軸の端部に固定されたシフトレバーと、そのシフトレバーの揺動駆動用のボールねじと、そのボールねじを駆動するモータとからなり、前記ボールねじが、ねじ軸と、そのねじ軸にボールを介してねじ係合するナットとを有し、前記ねじ軸とナットの一方を定位置にて回転自在に支持すると共に、他方を軸方向に移動自在に支持し、かつ回り止めし、その回り止めされて軸方向に移動可能なねじ軸またはナットと前記シフトレバーの先端部とを連結した構成を採用したのである。
上記の構成から成るチェンジ装置において、モータの駆動によりねじ軸とナットの一方を回転すると、他方が軸方向に移動し、その軸方向に移動するねじ軸またはナットによってシフトレバーが揺動し、変速操作軸が回動してシフトチェンジされる。 In order to solve the above-mentioned problems, in the present invention, in a change device such as a motorcycle that shift-changes by rotation of a speed change operation shaft, a shift lever fixed to an end of the speed change operation shaft, and the shift lever The ball screw has a screw shaft and a nut that is screw-engaged with the screw shaft via a ball. The ball screw has a screw shaft and a motor that drives the ball screw. One of the shaft and nut is rotatably supported at a fixed position, the other is supported so as to be movable in the axial direction, and the rotation is prevented. The structure which connected the front-end | tip part of the shift lever was employ | adopted.
In the change device configured as described above, when one of the screw shaft and the nut is rotated by driving the motor, the other is moved in the axial direction, and the shift lever is swung by the screw shaft or nut moving in the axial direction to change the speed. The operating shaft rotates and shift changes.

上記のように、この発明においては、モータで駆動されるボールねじによりシフトレバーを揺動させて変速操作軸を回動させるようにしたので、構成が簡単であると共に、部品点数が少なく、組付けに大きなスペースを確保することのない小型のチェンジ装置を得ることができる。
また、ボールねじは精度が高く、そのボールねじによって変速操作軸に固定されたシフトレバーを揺動させるようにしたので、精度の高い制御が可能である。 As described above, in the present invention, since the shift lever is swung by the ball screw driven by the motor to rotate the speed change operation shaft, the structure is simple and the number of parts is small. A small change device that does not secure a large space can be obtained.
In addition, the ball screw has high accuracy, and the shift lever fixed to the speed change operation shaft is swung by the ball screw, so that control with high accuracy is possible.

以下、この発明の実施形態を図面に基いて説明する。図１に示すように、自動２輪車に搭載されるエンジン１には、吸気管２および排気管３が接続され、上記吸気管２にキャブレタ４が組み込まれている。   Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, an intake pipe 2 and an exhaust pipe 3 are connected to an engine 1 mounted on a motorcycle, and a carburetor 4 is incorporated in the intake pipe 2.

エンジン１の下部にはミッションケース５が設けられている。ミッションケース５には変速操作軸６が回転自在に支持され、その変速操作軸６を回転させることによりミッションケース５内に組込まれた図示省略のギヤ変速装置がシフトチェンジされるようになっている。   A mission case 5 is provided below the engine 1. A transmission operation shaft 6 is rotatably supported on the transmission case 5, and a gear transmission (not shown) incorporated in the transmission case 5 is shift-changed by rotating the transmission operation shaft 6. .

変速操作軸６のミッションケース５から外部に位置する軸端部にはシフトレバー７が固定され、そのシフトレバー７を引上げることによってギヤ変速装置がシフトアップされると共に、シフトレバー７を押下げることによってギヤ変速装置がシフトダウンされるようになっている。   A shift lever 7 is fixed to a shaft end portion located outside the transmission operation shaft 6 from the transmission case 5, and when the shift lever 7 is pulled up, the gear transmission is shifted up and the shift lever 7 is pushed down. As a result, the gear transmission is shifted down.

図２は、シフトレバー７を揺動させる駆動装置１０を示す。この駆動装置１０は、ミッションケース５に固定されるハウジング１１を有し、そのハウジング１１にＤＣモータ１２と、そのＤＣモータ１２によって駆動されるボールねじ１３が支持されている。   FIG. 2 shows the drive device 10 that swings the shift lever 7. The drive device 10 includes a housing 11 fixed to the mission case 5, and a DC motor 12 and a ball screw 13 driven by the DC motor 12 are supported on the housing 11.

ボールねじ１３は、ねじ軸１４の外周に形成されたねじ溝とナット１５の内周に設けられたねじ溝間に図示省略したボールを組み込んだ構成とされ、上記ねじ軸１４の両端部はハウジング１１内に組込まれた軸受１６によって回転自在に支持されている。   The ball screw 13 has a configuration in which a ball (not shown) is incorporated between a screw groove formed on the outer periphery of the screw shaft 14 and a screw groove provided on the inner periphery of the nut 15. 11 is rotatably supported by a bearing 16 incorporated in the motor 11.

また、ねじ軸１４は、カップリング１７を介してＤＣモータ１２の回転軸に連結され、そのＤＣモータ１２によってねじ軸１４が回転駆動されるようになっている。一方、ＤＣモータ１２は、ＥＣＵ１８によって制御されるようになっている。   Further, the screw shaft 14 is connected to the rotating shaft of the DC motor 12 via the coupling 17, and the screw shaft 14 is rotationally driven by the DC motor 12. On the other hand, the DC motor 12 is controlled by the ECU 18.

ここで、ＥＣＵ１８は、シフトチェンジ用の手元スイッチ１９から入力される信号に基いてＤＣモータ１２の回転角を制御するようになっている。   Here, the ECU 18 controls the rotation angle of the DC motor 12 based on a signal input from the shift change hand switch 19.

ナット１５は、ハウジング１１に形成されたガイド孔２０に沿ってスライド自在とされ、かつ回り止めされている。   The nut 15 is slidable along the guide hole 20 formed in the housing 11 and is prevented from rotating.

ナット１５の外側面にはピン２１が設けられ、そのピン２１はシフトレバー７の先端部に形成されたガイド孔２２内に挿入されている。   A pin 21 is provided on the outer surface of the nut 15, and the pin 21 is inserted into a guide hole 22 formed at the tip of the shift lever 7.

実施の形態で示すチェンジ装置は上記の構造からなり、いま、手元スイッチ１９が操作されてＥＣＵ１８に信号が入力されると、ＤＣモータ１２が駆動し、ねじ軸１４が設定角度回転する。そのねじ軸１４の回転によりナット１５がねじ軸１４の軸方向に移動すると共に、シフトレバー７が揺動し、変速操作軸６が回転してシフトチェンジされる。   The change device shown in the embodiment has the above-described structure. Now, when the hand switch 19 is operated and a signal is input to the ECU 18, the DC motor 12 is driven and the screw shaft 14 rotates by a set angle. As the screw shaft 14 rotates, the nut 15 moves in the axial direction of the screw shaft 14, and the shift lever 7 swings, and the speed change operation shaft 6 rotates and shift-changes.

上記のように、チェンジ装置は、ＤＣモータ１２で駆動されるボールねじ１３を介してシフトレバー７を揺動させ、そのシフトレバー７によって変速操作軸６を回転させる部品点数の少ない簡単な構成であるため、コストも安く、しかも小型であるため、組付けに際して大きなスペースを確保する必要がない。   As described above, the change device has a simple configuration with a small number of parts for swinging the shift lever 7 via the ball screw 13 driven by the DC motor 12 and rotating the speed change operation shaft 6 by the shift lever 7. Therefore, since the cost is low and the size is small, it is not necessary to secure a large space for assembly.

また、ボールねじ１３は精度が高く、そのボールねじ１３のナット１５と変速操作軸６に固定されたシフトレバー７とを連結した構成であるため、ボールねじ１３のねじ軸１４の回転量に応じた角度分だけシフトレバー７を揺動させることができ、高い精度の制御を可能とすることができる。   Further, since the ball screw 13 has a high accuracy and is configured by connecting the nut 15 of the ball screw 13 and the shift lever 7 fixed to the speed change operation shaft 6, the ball screw 13 corresponds to the rotation amount of the screw shaft 14 of the ball screw 13. As a result, the shift lever 7 can be swung by an angle so that highly accurate control can be achieved.

実施の形態では、ＤＣモータ１２によりねじ軸１４を回転してナット１５を軸方向に移動させるようにしたが、ＤＣモータ１２によりナットを定位置で回転させ、そのナットにボールを介してねじ係合するねじ軸を軸方向に移動させるようにしてもよい。この場合、ねじ軸の軸端部の外周にピンを突設し、そのピンをシフトレバーの先端部に形成されたガイド孔に挿入する。   In the embodiment, the screw shaft 14 is rotated by the DC motor 12 and the nut 15 is moved in the axial direction. However, the nut is rotated at a fixed position by the DC motor 12, and the nut is screwed via a ball. The screw shafts to be combined may be moved in the axial direction. In this case, a pin is projected from the outer periphery of the shaft end of the screw shaft, and the pin is inserted into a guide hole formed at the tip of the shift lever.
